1.1 This International Standard establishes specifications for the stability of polyester-base safety film which has a heat-processed vesicular photographic image formed by nitrogen bubbles. It covers photographic film intended for LE-10 and LE-100 records.
1.2 This International Standard applies to photographic film in which the image layer is a discrete layer attached to a transparent support.
1.3 It applies to roll film and sheet film.
1.4 This International Standard characterizes only the inherent keeping behaviour of the film. However, the suitability of a film record after extended storage depends on both the inherent ageing characteristics of the film and the original image quality. The latter is discussed in annex B.
1.5 This International Standard applies only to vesicular photographic film intended and used as LE-10 and LE-100 storage copies. It does not apply to vesicular film records intended and used as "work" or "use" copies (as discussed in annex C). Most film records used in libraries are work copies and have to be durable. LE-10 and LE-100 storage copies should be stored in accordance with ISO 5466 and ISO 10214. The effects of heat and pressure are discussed in annex D and those of high humidity in annex E.
